HTC's after sales customer service is very slow and bad.

hey guys, just want to ask for your opinion. i really love htc one, it got everything i i like e.g beats, front camera, sexy body etc but the day when i want to buy new smartphone, i read complaints about htc one, the problems, replacement also in htc malaysia fb people complain a lot about after sales service so i buy s4 and now i regret because i dont like it. so is it worth for me to sell the s4 and buy htc one or just keep the s4? to be honest, i rarely used the s4. only day one mb.
